CentOS/Openeuler主机中，为一个网卡设置多个IP地址

1. 创建别名接口配置文件在/etc/sysconfig/network-scripts/目录下创建别名配置文件# 主接口配置文件如果不存在 sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0 # 别名接口配置文件 sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0:1 sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0:22. 配置主接口文件# /etc/sysconfig/network-scripts/ifcfg-eth0 TYPEEthernet BOOTPROTOstatic NAMEeth0 DEVICEeth0 ONBOOTyes IPADDR192.168.1.100 NETMASK255.255.255.0 GATEWAY192.168.1.1 DNS18.8.8.8 DNS28.8.4.43. 配置别名接口文件# /etc/sysconfig/network-scripts/ifcfg-eth0:1 DEVICEeth0:1 BOOTPROTOstatic IPADDR192.168.1.101 NETMASK255.255.255.0 ONBOOTyes # /etc/sysconfig/network-scripts/ifcfg-eth0:2 DEVICEeth0:2 BOOTPROTOstatic IPADDR192.168.1.102 NETMASK255.255.255.0 ONBOOTyes4. 重启网络服务#### CentOS 7 sudo systemctl restart network # 或者重启特定接口 sudo ifdown eth0 sudo ifup eth0 #### Openeuler nmcli con reload; nmcli con up eth0
